Description

If we want to use gcov in RTEMS to get code coverage in all system states, then we need some tweaks in GCC:

The linker set based gcov information registration is already included in GCC:

There is a discussion about how the gcov information can be transferred from the embedded system to the host:

The GCC integration needs to wait for the GCC 12 development start.
